Answer:

1. Hypothalamus

2. Optic chiasma

3. Corpora quadrigemina

4. Cerebellum

5. Thalamus

6. Medulla oblangata

7. Corpus Collosum

8. Fornix

9. Cerebral aqueduct

10. Midbrain

Explanation:

The hypothalamus is a small central region of the brain that regulates body temperature by responding to both internal and external stimuli and also produces the antidiuretic hormone (ADH) in order to trigger the reabsorption of water in the kidneys. The optic chiasma is a special sensory structure located along the visual pathway, directly in front of the hypothalamus, which is crucial to vision. The corpora quadrigemina, also known as quadruple bodies, are reflex centers located in the mesencephalon (midbrain) that regulate the position of the head and eyes in response to somatic stimuli. The cerebellum is a part of the brain located behind the top part of the brain stem which is involved in motor movement regulation and balance control. The thalamus (massa intermedia) is a paired gray matter structure found near the center of the brain that plays vital roles associated with sensory and motor functions of the brain. The medulla oblangata (medulla) is a structure located at the base of the brain involved in the regulation of sensory, motor, and mental functions (e.g., breathing, pain modulation, etc). The corpus callosum (the callosal commissure) is a bundle of nerve fibers that connects the two hemispheres of the brain. The fornix (agenesis of the corpus callosum) is a large interhemispheric commissure that connects neurons in the right and left hemispheres. The cerebral aqueduct (aqueduct of Sylvius) is a narrow channel that connects the third and fourth ventricles, thus allowing the cerebrospinal fluid to flow between the ventricles. Finally, the midbrain o 'mesencephalon' is a small region located in between the forebrain and hindbrain, which is involved in auditory and visual processing, eye movement and coordination.

True or false: sensitivity differences during light and dark adaptation result, at least in part, from the difference in bleachi

arsen [322]

True, photopsin and rhodopsin are the photoreceptor proteins found in the cones of the retina and are the basis of color vision.

<h3>What is the function of rhodopsin?</h3>

The retina contains a chemical compound called rhodopsin. It is responsible for converting light into electrical impulses that the brain interprets as vision. Nerve fibers from the retina come together at the back of the eye and form the optic nerve, which carries electrical impulses to the brain.

<h3>What is the function of the retina?</h3>

The function of the Retina is to capture light through the cornea, pupil and lens, and, through the optic nerve, convert it into neural signals and send them to the brain, which transforms it into visual recognition.

With this information, we can conclude that A very thin layer of light-sensitive tissue, located at the back of the eye, the retina is formed by millions of photoreceptor cells, which capture, record, decode light waves and, through the optic nerve, send them to the brain, where the vision.

Suppose you have engineered a plasmid vector in order to produce a functional animal protein in

Elodia [21]

Although E. coli may have translated it correctly, it might not have the same enzymatic modification process present in the original organism where the genetic sequence was taken from. It might be worth trying this enzymatic modification, also called post-translational modification - it is done in order to make some changes to the produced protein (such as introducing a phosphate group) making it functional.

when the atmosphere changes due to the human activities, how does the change affect humans in return?

Valentin [98]

Answer:

Climate change effects such as hunger, poverty and diseases like diarrhea and malaria, disproportionately impact children; about 90 percent of malaria and diarrhea deaths are among young children. Children are also 14–44 percent more likely to die from environmental factors, again leaving them the most vulnerable.

In order to improve patient relations, a family practitioner should ____

Helen [10]

In the field of medicine we have a short adage that goes, "To cure sometimes, to treat often, to comfort always." Some say it was Hippocrates himself who said this. With that in mind, doctors should always have the patient's welfare in mind always. To improve relations with the patient, the doctor must do a lot of things to show respect. One of them includes simply sitting on a chair with an open stance and leaning slightly forward at an angle while the patient is talking to show that you are interested in what he or she has to say. Never hold the door knob while the patient is still talking as this is a sign that you want him to leave as soon as possible. Never look at far away things, like paintings on the wall or a clock, while the patient is talking because this is another sign of disinterest. And always allow the patient to express his or her self fully without interruption. There are more ways to improve patient relations but these are some good pointers to begin with.
